Nitric oxide functions as a signal in plant disease resistance
Article Abstract:
The induction of hypersensitive cell death in soybean cells is potentiated by nitric oxide (NO) by reactive oxygen intermediates (ROIs). NO acts independently of these intermediates to induce genes to synthesize protective natural products. There is a marked complementarity between NO and ROI signal functions, with independent activation of complementary gene sets. NO acts in the plant hypersensitive disease-resistance response, and seems to be vital for preventing pathogen spread from an inoculation site.

Airborne signalling by methyl salicylate in plant pathogen resistance
Article Abstract:
The role of methyl salicylate (MeSA) in the defense response of plants is investigated. MeSA is a major volatile compound produced by tobacco plants injected with tobacco mosaic virus. It is synthesized from salicylic acid. It may act as an airborne signal which activates disease resistance and the expression of genes related to defense in nearby plants and in the healthy tissues of the infected plant.
